BUBBLER HEAD I Filed March 2, 1936 'atented Aug. lb, 1937 2,089,894 BUBBLER HEAD 3 Claims.

This invention relates to bubbler heads such as used with drinking fountains.

Many of the bubbler heads now in use are objectionable for several reasons. For example water dripping from the mouth of the user has fallen back onto the outlet and frequently con-' taminated it. The outlet has usually been located where the user could press the mouth thereagainst with result that contamination has thus been transmitted. The bubbler heads have also been so formed and located that persons have been able to deflect the jets of water onto others. Injury tov users has also resulted from playful ducking into the fountain and consequent violentcontact with the outlet nozzle.

The object of the present invention is to remove the objections heretofore noted by providing a bubbler head which will throw the water jet laterally so that saliva or other secretions will not fall upon the nozzle, means being employed whereby any obstruction of the outlet will result in the diversion of the stream downwardly so that it cannot be projected onto nearby persons.

A further object is to so construct and locate the nozzle that it will be maintained clean and cannot be reached by the mouth of the user.

Another object is to provide the nozzle with a guard affording maximum protection from the mischievous practice of pushing the head of the user down toward the nozzle.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claims, it being understood that changes may be made in the construction] and arrangement of parts without departing from the spirit of the invention as claimed.

In the accompanying drawing the preferred form of the invention has been shown.

In said drawing Figure 1 is at front elevation of the bubbler head in position for use.

Figure 2 is a vertical section through the bubbler head on line 2-2, Figure 1.

Figure 3 is a top plan view.

Figure 4 is a bottom plan view.

Referring to the figures by characters of reference, l designates a sleeve having a screw threaded socket 2 whereby it can be attached to a water pipe 3 having any suitable valve t. The upper end of the sleeve has an integral cup-like guard 5 in the form of an inverted cone a segment of which is removed as shown at E to provide a clearance. A rounded flange '1 is provided along the top edge of the guard while extended across the lower portion of the guard is a diametrical ridge 8 from which extend downwardly diverging draining surfaces forming the bottom of the guard. One of these surfaces 9 extends backwardly and cooperates with the Wall of the guard to provide a recess having a drain aperture 29 opening downwardly through said wall. The other inclined surface H extends for- 10 wardly to the bottom. of the clearance S and merges into an ear !2 which projects outwardly from the head and the bottom surface of which forms a shoulder l3 disposed at an angle to the upper end of sleeve l.

An outlet bore l4 opens into the socket 2 and is inclined upwardly and forwardly so as to open through and at right angles to the surface ll. The upper or outlet end of this bore is enlarged or counterbored, as at l5 and a by--pass i6 extends downwardly from this counterbore and opens through the shoulder l3.

It will be apparent that when valve 4 is opened a jet of water will be discharged from the nozzle formed by ear l2 and the bore therein and this jet will be projected upwardly and forwardly through the clearance 6 so that the mouth of the user can be brought against the jet at a point outside of the bubbler head. prevents the mouth from coming against the nozzle and should any saliva or other secretions drop into the head the same will be washed from the inclined surfaces, flowing off either at the drain opening H! or over the ear l2. Thus the device will be kept in a sanitary condition and danger of contamination therefrom is reduced to the minimum.

Should a finger be placed over the upper surface of the nozzle to close the water outlet, the water would not be diverted laterally as can be done with most bubbler heads, but, instead the diverted water will be expelled downwardly through the by-pass l6. As the shoulder 13 extends close to the surface of the sleeve I it' is not possible for anyone to place a finger where it completely closes the by-pass.

What is claimed is:

1. A bubbler head including a member having a socket for attachment to a water supply, and a guard extending from the member and providing a clearance, an inclined surface at the bottom of the guard and partly surrounded thereby, said surface being extended downwardly to the bottom of the clearance, a bore extending from the socket and inclined upwardly to and opening through said inclined surface, said bore being positioned for directing a Water jet upwardly and side of the outlet portion outside of said member, said by-pass being positioned to receive and discharge liquid standing in the upper portion of the bore and matter falling into said bore.

3. A bubbler head including a socket member for attachment to a Water supply, a flared guard on the upper end of said member, a portion of the Wall of the guard being removed to provide a clearance, downwardly diverging surfaces forming the bottom of the guard and the top of the through the projecting from the member at the bottom of the clearance and forming a continuation of said inclined surface,
